3. Skittles Activity Find the volume of the cylinder
Fill the cone with skittles, and dump into the cylinder. Repeat until cylinder is full.
On average, how many cones fit into the cylinder?
Using this information, create a formula for the volume of a cone.

4. Conversion: Skittles to cm3
How many cm3 is 1 skittle?
This is a type of conversion that (probably) CAN’T be found on Google. So how can we create it?
Hint: Find the volume of the cylinder in cm, Then find the average number of skittles that fit into the cylinder.
